Title: Manufacture of hybrid integrated circuit
Inventor: ARAI SUKEHITO
IPC: B23K3/06
Filed: 1987-06-11
Abstract: PURPOSE:To apply a fixed quantity of solder cream positively by conducting test application and starting an applying process again when an applying process is suspended. CONSTITUTION:When a solder-cream applying process is suspended, solder cream is applied at least once or more on the outside of a hybrid integrated circuit substrate 2, or pressure larger than pressure applied to a dispenser 4 is applied, a reservoir section 5' is formed at the nose section of the dispenser 4 and the reservoir section 5' is gravity-dropped, and the solder-cream applying process is started again. Accordingly, since test application is performed before the applying process is started again, solder cream 5 does not collect or cure at the nose of the dispenser 4, thus positively applying solder cream 5 onto the substrate 2.

Title: Device for generating character
Inventor: NAGASAKA FUMIO
IPC: G09G5/24
Filed: 1992-06-05
Abstract: PURPOSE:To form a character shape adopting an intention on design and easy to make out even when the number of pixels necessary for displaying a character is insufficient compared to the complexity of the character shape. CONSTITUTION:By a character generation means 10, when it is known that the size of a required character is smaller than a correction limit size by comparing the required character with the correction limit size 16 described in character data 14, first of all, the character shape larger than the correction limit size is generated in an image memory 9. Then, a horizontal correction template 20 is read in and the arrangement of the pixel is rearranged by using an OR circuit 8 accorsing to the change of 0/1 of the bit of the value. At this time, while the same value of the bit in the template is continued, the pixel group aligning on the same straight line in a horizontal direction is superposing- processed. Further, when the bit value is changed in the template, the superposing-processed pixel group is recorded as the new pixel group. Similar processing is executed by using a vertical correction template 19 in a vertical direction, as well and the character is reduced to the required size.

Title: Method of constructing converter using trapezoidal brick
Inventor: SAITOU MASAO
IPC: F27D1/04
Filed: 1980-10-21
Abstract: PURPOSE:To prevent a wedge-shaped joint gap from being formed at a conical part of a converter by a method wherein trapezoidal bricks are piled up at an appropriate inclination angle gainst a converter which has a conical type furnace shell. CONSTITUTION:When constructing a lower part of the furnace body of a converter or the like, the trapezoidal bracks are used which have a fixed thickness (t) and in which the widths (a), (c) on the side of the wall of an iron shell 1 as a viewed in the trhickness direction and the widths (b), (d) on the side of the furnace center are different from each other. When the bricks are placed with the cross-sectional surfaces of the bricks in parallel to the iron shell 1, the difference berween the furnace circumference l' at point A and that l at point B is absorbed by the difference (a-c) of the brick width across the thickness of the brick and, accordingly, the bricks can be placed without generating any gaps therebetween. By using trapezoidal bricks, it is made possible to minimize or completely eliminate joint gaps even in the case of building up the bricks at an inclination angle of alpha against the horizontal line for the iron shell 1. Accordingly, the useful life of the converter can be prolonged greatly.

CONSTITUTION: A dew-point sensor 10 is provided with a sensor surface 18 which is exposed to a gas to be measured from which steam is condensed when the gas is cooled to its dewpoint temperature and two electrode structures 20 and 30 having teeth 22 which are respectively coated with moitureinsensible insulating layers 40 and arranged in parallel at regular intervals on the surface 18 as electrode sections. Since the intervals 42 between the parallel teeth 22 of the structures 20 and 30 must be designed properly so that the intervals can correspond to the diameter of the water drop formed during the shortest period of time, the intervals are formed to <50μm which is equal to the order of the diameter of the largest condensed water drop, preferably, to about 20μm.  The insulating layer 40, in addition, is formed of a tantalum oxide which is not sensible to condensed moisture and the thickness of the tantalum opxide is adjusted to <1μm by oxidizing the surface of the tantalum constituting the structures 20 and 30.
